Placerville — Development Standards

Last reviewed: July 2, 2026

Overview

This page synthesizes the development standards (setbacks, height, lot coverage, density, FAR and related controls) found in the City of Placerville zoning ordinance (Title 10). It pulls the operative dimensional rules for the City’s zones and explains how they are applied in practice, with district‑by‑district detail, practical guidance, and explicit code citations so you can verify requirements on a parcel‑by‑parcel basis. Where the ordinance is silent or parcel‑specific, the entry notes that you must verify with the City.

How to use this page

• If you are preparing a site plan, first check the zoning district for your parcel and the controlling development standards summarized below.
• Cross‑check design and parking requirements and whether your site falls into any overlay district or historic district (Historic Preservation) that can change setbacks or require design review.
• Look up accessory dwelling rules for ADUs on the Placerville ADUs page and confirm building code compliance with the California Building Standards Code.

District-by-district standards

Below are the most decision‑relevant zoning districts and the ordinance provisions that control setbacks, heights, lot coverage, FAR/density and special rules. Each district subsection states the purpose, typical permitted uses, key dimensional standards, and where it applies in the code (with direct § citations).

R-1A — Single-Family Acre Residential

• Purpose & uses: Low‑density single‑family and accessory uses (one single‑family dwelling, guest quarters, accessory dwelling units allowed). See § 10-5-5.
• Key dimensional standards:
  • Maximum density: 1 du/acre (§ 10-5-5).
  • Minimum parcel area: 1 acre (§ 10-5-5).
  • Maximum building coverage: 35% (§ 10-5-5).
  • Minimum parcel width: 100 ft (§ 10-5-5).
  • Maximum building height: 35 ft (§ 10-5-5).
• Notes: ADUs are allowed subject to § 10-4-12 (see ADU subsection below).

R-5 — Very High Density Multi‑Family Residential

• Purpose & uses: Multi‑family housing, higher densities, supportive uses; includes objective minimum density requirements tied to State law. See § 10-5-17 and § 10-5-12 subsections describing R‑5 rules.
• Key dimensional standards (R‑5 general regs at § 10-5-12 / § 10-5-13):
  • Residential density: Minimum and maximum established at rezoning; default minimum 20 du/acre and allows up to 24 du/acre where applied (§ 10-5-12).
  • Minimum parcel area: 6,000 sf (or 2,000 sf per unit for attached forms) (§ 10-5-12).
  • Maximum parcel coverage: 60% (§ 10-5-12).
  • Minimum yards: Front 20 ft, sides 10% of parcel or 10 ft (whichever less), rear 15 ft (zero where common wall) (§ 10-5-12).
  • Maximum building height: 40 ft (§ 10-5-12).
• Notes: Design review / site plan review required for most R‑5 projects (§ 10-5-12(E)(3)). Verify CEQA and specific rezoning conditions which may alter allowable density.

CC — Community Commercial

• Purpose & uses: Neighborhood and community retail and service uses; ADUs allowed where residential uses exist. See § 10-5-? (Community Commercial material in the code).
• Key dimensional standards:
  • Minimum parcel area: 10,000 sf (§ 10-5-?).
  • Maximum building coverage: 25% (§ 10-5-?).
  • Minimum yards (examples): arterial 25 ft, collector 20 ft, subcollector 15 ft (§ 10-5-?).
  • Maximum building height: 30 ft (§ 10-5-?).
  • Floor area ratio (FAR): 0.25 (§ 10-5-?).
• Notes: No parking within setback areas; setback areas required to be landscaped and reviewed by the Planning Commission (see landscaping rules and landscaping and screening).

HWC — Highway Commercial

• Purpose & uses: Freeway/travel‑oriented uses (gas stations, fast food, hotels). See § 10-5-17.
• Key dimensional standards:
  • Maximum building height: 30 ft (§ 10-5-17).
  • Floor area / per center limits: Max floor area per center 5,000 sf, per occupancy 3,000 sf (§ 10-5-17).
  • Minimum landscape requirement: 25% (§ 10-5-17).
• Notes: Typical uses and hours of operation are controlled and some uses require a conditional use permit (§ 10-5-17(B)–(C)).

PDI — Planned Development Industrial

• Purpose & uses: Industrial/manufacturing, incubator and tourist‑oriented uses. See § 10-5-22.
• Key dimensional standards:
  • Minimum parcel area: 6,000 sf (§ 10-5-22(D)(1)).
  • Maximum building coverage: 60% (§ 10-5-22(D)(2)).
  • Maximum building height: 40 ft (§ 10-5-22(D)(4)).
• Notes: PDI allows outdoor storage and processing; design and layout expectations reflect industrial needs (§ 10-5-22).

PF — Public Facilities

• Purpose & uses: Governmental and non‑profit public uses (libraries, municipal facilities). See § 10-5-20.
• Key dimensional standards:
  • Minimum lot area: 6,000 sf (§ 10-5-20).
  • Maximum building height: 45 ft (§ 10-5-20).
  • Yards/setbacks: Front 10 ft (but 20 ft when abutting residential), side 10 ft (§ 10-5-20).

BP — Business‑Professional

• Purpose & uses: Offices and professional services. Refer to § 10-5-13 for detailed requirements.
• Key dimensional standards: see § 10-5-13.

Accessory Dwelling Units (ADUs) — summary of development standards

• ADUs are allowed in most residential and many non‑residential zones subject to the City’s ADU rules in § 10-4-12. ADU setbacks for new detached ADUs: minimum side/rear setbacks 4 ft, street side yard 10 ft, front yard equals the district front setback but may be reduced to permit an 800 sf ADU (§ 10-4-12(f)).
• ADU height: attached ADU height = same as primary dwelling; detached ADU cannot exceed the zone maximum or two stories; City rules note state ADU limitations and reference state law (verify state allowances) (§ 10-4-12(g)).
• Lot coverage: ADUs are not counted when calculating maximum lot coverage per the Placerville ordinance (§ 10-4-12(h)).
• For state‑driven minimums and additional height/parking rules for ADUs see the ADU handbook included in the materials (state citations summarized there).

Practical guidance & comparisons (plain‑English synthesis)

• Where a zone lists both maximum lot coverage and a separate landscape percentage (for example 25% landscaping in many commercial zones), the landscaped area is measured in addition to building coverage limits unless the code explicitly states otherwise—confirm with the planner. See § 10-5-17 and § 10-5-? (CC) for examples.
• The ordinance regularly grants the Development Services Director authority to approve limited adjustments or minor deviations (for front/side/rear yards, coverage, height of fences, etc.). The minor deviation criteria and process are in § 10-3-5 (minor deviation rules) and the specific zone may reference that allowance. Use that route where strict adherence is infeasible; adjacent owner notification requirements apply.
• If your site is part of a rezoning, PD overlay, or subject to CEQA mitigation, the allowable density/standards may be site‑specific and set at rezoning—verify the rezoning ordinance and the applicable PD conditions (§ 10-4-2(D)4 and PD overlay rules).

Across planning submittals you will frequently need to coordinate:

• Parking requirements (see the City’s Parking page and the zoning schedule), site landscaping (Landscaping and Screening), signage (Signage) and possible design review (Design Review).

Checklist

• Confirm property zoning district and any overlay or historic overlay that changes setbacks or design rules (verify with § references).
• Verify dimensional standards: maximum height, lot coverage, minimum setbacks and FAR/density for the district (see district § above).
• If proposing an ADU, confirm ADU-specific setbacks, height, and the ADU exemption from lot coverage (§ 10-4-12).
• Prepare site plan showing building footprints, parking layout (see Parking), landscape areas (Landscaping and Screening), and demonstrate compliance with front/side/rear setbacks.
• Determine whether design review or site plan review is required (R‑5 and some other zones require site plan review) and consult the Design Review page.
• If seeking relief (minor deviation, variance, density bonus) review the procedures in §§ 10-3-5, 10-12-10, and the variance chapter (Variances and Exceptions).

Risks & Ambiguities

Plain‑English Summary

Placerville’s zoning (Title 10) sets district‑specific rules you must meet: maximum heights (commonly 30–45 ft depending on zone), lot coverage limits (often 25–60%), established front/side/rear setbacks, and in some commercial zones a 0.25 FAR and a 25% landscaping requirement. ADUs are specifically allowed with small setbacks and are not counted toward lot coverage; minor deviations and density bonuses are available through established procedures. Always confirm parcel‑specific overlay conditions or rezoning conditions with the City. See § 10-4-12, § 10-5-5, § 10-5-12, § 10-5-17, and § 10-5-22 for the controlling language.
